You can still use the Update-Database command.

Update-Database -Migration  -Context 

However, judging by the name of your migration i'm assuming it's the first migration so that command may not work. You should be able to delete the entry from the __MigrationHistory table in your database and then run the Remove-Migration command again. You could also delete the migration file and just start again.
